1. An apparatus for noninvasive measurement of glucose through near-infrared spectroscopy, comprising:

  • a base module comprising a grating and a detector array, said base module further comprising;

    means for bias correcting one or more of spectral data collected in (X) and glucose concentration data (Y);

    a sampling module, securely and removeably attachable to a sample site, and coupled to said base module, said sampling module comprising an illumination source; and

    a communication bundle for carrying optical and/or electrical signals between said base module and said sampling module, and for carrying power to said sampling module from said base module,wherein said base module further comprises means for calibrating to an individual or a group of individuals based upon a calibration data set comprised of paired data points of processed spectral measurements and reference biological parameter values.
